Dobey, if it was anyone else but you I think I'd block the post! Amazing what can be done to that gun. It probably needs to be stressed that all parts are thoroughly dried. And you did mention using compressed air to do this.

Yes I blow it all out after I am done, I have been cleaning my gbb guns like this for a few years and never had a problem with it. As you can see in the video and my other picture posts I have no rust at all on the guns from doing this.

This gun is about a year old now, and has been cleaned this way more than 20 times.
